source command



source | items 
       / prefix() 
         import()   list    centre(0,0,0) debug
         export()   delete  energy()
         read       display dir(0,0)
         write      inspect 

Purpose

Handles source setup

Parameters

items
For read specifies the name of the source file to be read.
Otherwise specifies the primary particle (projectile) type.
prefix(prefix)
For output options only: file name is prefixed with <prefix>.
import()
Not yet implemented.
export(fmt)
Not yet implemented.
read
Read source data file specified by items
write
Not yet implemented.
list
List source data.
delete
Delete source data.
display
Not yet implemented.
inspect
Show some internal info about the current source data.
centre(x,y,z)
Specifies the source position (cm).
energy(e)
Specifies the primary particle energy (electrons and photons in keV, ions in MeV/u).
dir(thmin[.thmax],phmin[,phmax])
Specifies emission direction, polar and azimuth angles in degree. If two numbers, thmin,phmin, are given they are interpreted as single polar and azimuth angle, respectively. If four numbers, are given they are interpreted as polar and azimuth angular range, with isotropic emission. A single * denotes isotropic emission in all directions.
debug
Debug switch. Lots of output !

Remark

This command implements a simple point source. More spatial distributions are possible using external source files.

Examples

   source edist.src / read
Read an external source file
   source H1+ / dir(0,0) e(1.0) centre(0,0,-1E-4)  
Specifies protons of 1 MeV/u energy, starting at z=-1E-4cm in z-direction.
   source e- / dir(*) e(1.0) centre(0,0,0)  
Specifies electrons of 1 keV energy, starting at 0, emitted isotropically in all directions.
